Qualified Usage of Drying Agents Waste on the Base of Silica gel for Polyurethane Composition.

Abstract

There was examined a possibility of industrial waste of silica gel usage as filling agent of castable polyurethanes. There were reported results of filling agent’s polydispersity assessment, as well as viscosity of reaction system depending on filling ratio. There was examined change of wetting properties of polyurethane composition at a time depending on filling ratio. There was showed that under filling of castable polyurethanes strength characteristics of samples rests on the level of non-filling samples. There was proved that by means of filling of silica gel waste could to decrease time of synthesis process of urethane polymers that allows decrease of opportunity costs and improve environmental characteristics of process at the expense of usage of lesser quantity of polyurethanes, filling with industrial waste of silica gel.
